Chediak-Higashi syndrome is a childhood disorder that interferes with immune system function. It is also known as Begnez-Cesar syndrome, leukocyte anomaly albinism or defect in natural killer lymphocytes.
It was first described in 1943 by Dr Beguez-Cesar.

Chediak-Higashi syndrome is an autosomal recessive condition caused by a mutation on the LYST gene. It is often due to parental consanguinity. The LYST gene affects the creation and maintenance of storage granules and causes problems with the transport of a protein across cells.
